Bug ID: 113327
Summary: std::sleep_for(std::chrono::hours::max()) returns
immediately
Product: gcc
Version: 13.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: fchelnokov at gmail dot com
Target Milestone: ---
Found in https://stackoverflow.com/a/77795017/7325599
The problem is that the following program returns immediately (instead of long
wait):
#include <chrono>
#include <thread>
#include <iostream>
int main(int argc, char * argv[])
{
std::this_thread::sleep_for(std::chrono::hours::max());
}

--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Converting hours::max() to milliseconds overflows and produces a negative
value.
